Description

Technical Field

[0001] The invention belongs to the technical field of bridge-type printing structures, and in particular relates to a bridge-type printing structure based on a slide rail structure. Background Art

[0002] Bridge-type printing structure refers to the process of 3D printing, through a specific printing path and stacking method, to build a suspended part similar to a bridge structure without the need for additional support structures. 3D printing technology is based on a three-dimensional model established by a computer, and constructs objects by adding materials (such as powdered metal, plastic and other bondable materials) layer by layer. In the bridge-type printing structure, the print head moves along a preset path, depositing materials layer by layer to form a complex structure with a suspended part.

[0003] At present, during the use of the existing bridge-type printing structure, the printing components are usually driven by electric slide rails. Since the slide rails are important components in the bridge-type printing structure, they need regular maintenance. However, the slide rails in the traditional bridge-type printing structure are often installed on the frame by bolts, so it is very inconvenient to disassemble and maintain them. If the maintenance is performed directly on the frame, it will be more limited and inconvenient for the staff to operate, thereby reducing the maintenance efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a bridge-type printing structure based on a slide rail structure, aiming to solve the problem that during the use of the existing bridge-type printing structure, the printing assembly is usually driven by an electric slide rail, and the slide rail is an important component in the bridge-type printing structure, so it needs regular maintenance. However, the slide rail in the traditional bridge-type printing structure is often installed on the frame by bolt fixing, so it is very inconvenient to disassemble and maintain. If the maintenance is directly on the frame, it will be more limited and inconvenient for the staff to operate, thereby reducing the maintenance efficiency.

[0005] To achieve the above object, the present invention provides the following technical solution: a bridge-type printing structure based on a slide rail structure, comprising a printer frame, the top of the printer frame is connected to an electric slide rail and a slide rail, the top of the electric slide rail is connected to an electric slide seat, and the top of the electric slide seat is connected to a printing assembly; The two ends of the electric slide rail are respectively connected to a fixing block, and a limiting slot is provided at the end of the fixing block. The top of the printer frame is connected to two first mounting seats, and a bidirectional screw rod is inserted through one end of the two first mounting seats, and a knob is connected to one end of the bidirectional screw rod. A guide rod is connected inside the first mounting seat, and the outer wall of the bidirectional screw rod is threadedly connected to two threaded connection blocks, and the tops of the two threaded connection blocks are connected to L-shaped limiting plugs.

[0006] As a preferred bridge-type printing structure based on a slide rail structure of the present invention, the bidirectional lead screw forms a rotation connection structure with the first mounting seat through a bearing.

[0007] As a preferred embodiment of a bridge-type printing structure based on a slide rail structure of the present invention, one end of the two threaded connection blocks is sleeved on the outer wall of the guide rod.

[0008] As a preferred embodiment of a bridge-type printing structure based on a slide rail structure of the present invention, the limiting slot is adapted to the size of one end of an L-shaped limiting plug block.

[0009] As a preferred bridge-type printing structure based on a slide rail structure of the present invention, the tops of the two first mounting seats are connected with positioning protrusions, and the bottom of the fixing block is provided with a positioning groove.

[0010] As a preferred bridge-type printing structure based on a slide rail structure of the present invention, the top of the slide rail is connected to a slide seat, the top of the slide seat is connected to a connecting seat, both ends of the connecting seat are connected to a second mounting seat, and a cleaning brush is provided at the bottom of the second mounting seat.

[0011] As a preferred bridge-type printing structure based on a slide rail structure of the present invention, the cleaning brush is fitted to the slide rail.

[0012] As a preferred bridge-type printing structure based on a slide rail structure of the present invention, a T-slot is provided at one end of the second mounting seat, a spring is arranged inside the second mounting seat, one end of the spring is connected to a movable block, one end of the movable block is connected to a mounting plug-in block, the outer wall of the movable block is connected to a shift block, the top of the cleaning brush is connected to a T-block, and the top of the T-block is provided with a mounting slot.

[0013] As a preferred bridge-type printing structure based on a slide rail structure of the present invention, one end of the mounting plug-in block passes through the interior of the extended T-slot.

[0014] As a preferred bridge-type printing structure based on a slide rail structure of the present invention, the cleaning brush can form an elastic snap-fit ​​structure with the second mounting seat through a T-slot, a spring, a movable block, a mounting plug block, a shift block, a T-block, and a mounting slot.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By turning the bidirectional lead screw counterclockwise through the knob, the two threaded connection blocks connected by threads on its outer wall can move toward each other along the guide rod. As the two threaded connection blocks move toward each other, one end of the L-shaped limit plug block on the top of the two threaded connection blocks will disengage from the limit slot at the end of the fixed block. After disengagement, the electric slide rail can be separated from the printer frame, thereby allowing the electric slide rail to be easily removed from the printer frame.

[0016] By installing a slide rail, a slide seat and a connecting seat at the other end of the printing component, when the electric slide rail drives the printing component to move, the slide rail, the slide seat and the connecting seat can assist the movement of the other end of the printing component, and because the cleaning brushes at both ends of the connecting seat are in contact with the slide rail, the cleaning brushes can clean the surface of the slide rail during the movement of the printing component, thereby preventing debris from falling on the slide rail and affecting the movement of the printing component.

[0017] The movable block is moved by the shift block, so that the movable block drives the installation plug block to contract, so that one end of the installation plug block can be disengaged from the installation slot at the top of the T-block. At this time, the T-block can be taken out of the T-slot to realize the disassembly of the cleaning brush, thereby facilitating the subsequent processing of the bristles of the cleaning brush.
